Mozilla's getting a new look. What do you think? https://mzl.la/brandsurvey

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Summary

Returns the maximum number of pixels that the document can be scrolled horizontally.

Syntax

xpix = window.scrollMaxX
  • xpix is the number of pixels.

Example

// Scroll to most right of the page
var maxX = window.scrollMaxX;

window.scrollTo(maxX, 0);

Notes

Do not use this property to get the total document width, which is not equivalent to window.innerWidth + window.scrollMaxX, because window.innerWidth includes the width of any visible vertical scrollbar, thus the result would exceed the total document width by the width of any visible vertical scrollbar. Instead use document.body.scrollWidth. See also window.scrollMaxY.

Specification

This is not part of any specification.
